Measuring the height and weight of an infant is a very important practice, since the information provided is of great importance for determining the health and development of the child. This is a very simple method of analysis that allows you to get a lot of information about how the baby eats, what health problems he may have, whether all the nutrients are enough, etc. Let's see what is the norm of weight at what height.
Baby weight at birth
The weight of an infant at birth can vary considerably and depends on many factors. The normal weight range of newborns is usually between 2.5 and 4.5 kilograms. However, we should not forget that weight at birth can fluctuate outside this range.
If we talk about weight at birth, it is influenced by several factors:
Genetics | If parents have a lot of birth weight, then their babies can have a high birth weight. True, not only the phenotype of parents, but also distant relatives affects here. There are situations that parents were lightweight, but their grandfathers were big. And the child is born with parameters that are more consistent with those that great-grandfathers had. Weight standards for children may vary depending on what her relatives were. |
Duration of pregnancy | Newborns who are born after full term gestation (approximately 37-40 weeks) tend to gain more weight compared to those who are born prematurely. This, in principle, is logical. |
Gender | Boys usually have a slightly higher birth weight than girls. |
Maternal condition during pregnancy | If she had any medical conditions, was malnourished or had any medical complications, this can also affect the formation of the fetus and the weight of the newborn baby. |
In addition, there is a correlation between weight and ethnicity. Some other factors are possible, but these are the main ones.
How to measure the height of a baby?
First of all, you need to choose a suitable place. To accurately measure height, choose a flat surface, such as a children's table or gurney. Make sure the child is lying upright on his back, with his legs straightened and arms spread along his body.
You also need to use the correct device. To measure height, you can use a children's meter or a medical growth meter. The meter must be straight, stable and correctly marked.
To measure the height of the child, you will need to perform the following steps:
It is recommended that your child's height be measured regularly (for example, monthly in the first year of life and then every few months) to track changes in their growth and development.
The growth of older children is already easier to measure. To do this, you just need it to stand against the wall and make a mark at the level of the top of the head. And then just measure the distance between the floor and that mark.
Rate of weight gain and height of infants
Let's present a table that describes the normal rate of weight gain and height in children under one year of age. It is important to understand that all these figures are approximate and depend on many factors. Certain deviations are possible, but to understand whether this is a variant of the norm or not, it is better to consult a doctor.

If you take the weight of the child by month, it may even differ. Specific trends are important here, as well as the ratio of weight and height.
Factors affecting a child's height and weight
Previously, we described the factors that affect the height and weight of a newborn baby. Some of them remain (for example, genetics, ethnicity and gender). However, some parameters, such as nutrition, are new. For example, it is very common that a mother thinks that she is breastfeeding her baby, although she has very little milk. As a result, the baby is constantly malnourished, which leads to weight loss of the baby.
In addition, the height and weight of the child is affected by the activity of the child. When she begins to crawl, this is an additional calorie expenditure that must be considered in the diet.
Height and weight of a child under 1 year old and feeding
I must say right away that breast milk is the best source of nutrition for babies because it contains all the necessary nutrients and antibodies to protect against infections. Practice has shown that children who were fed artificial formulas get sick somewhat more often compared to others.
If breastfeeding is not possible, you should discuss well with your pediatrician the choice and correct application of the formula for feeding.
Newborns often need feeding every 2-3 hours, and babies aged 1-6 months every 3-4 hours. Feeding regularly helps ensure you get enough calories and nutrients.
It is very important to regularly measure the weight and height of the child and observe their changes. This will help you make sure that your child's weight increases according to the norm. If you see that your child is losing weight, it may indicate that they are not getting enough calories.
It is necessary to monitor the weight of the child at an older age – at 2, 3, 4, 5 years or more. The body grows, its calorie needs change, but parents may habitually feed the child in the same way and not trust the one when he asks for more (although he may be objectively hungry). Or vice versa, giving the child too much, because of which his weight increases. Yes, and children often ask to eat the wrong that they are hungry, but because it is delicious. Kids need to be taught moderation in food.
Here the logic is very simple – if a child gains weight faster than age norms, he overeats, if he loses – he is malnourished.
When to see a doctor?
In general, you need to regularly visit a doctor. Then you don't even need to weigh and measure the child yourself. This will be done by a family doctor. In addition, he will make a comprehensive assessment of the health of the baby. But, in general, if a child consistently loses or gains weight too much, it is necessary to consult a specialist to correct this problem.
Remember that you are your child's best protector. If you feel that something is wrong with her, do not hesitate to contact your doctor or medical specialists for medical attention and advice.
Table of height and weight of the child by months and years
The more years a child is, the greater the possible range of height and weight. As well may vary the ratio of weight to height , this is normal. The body develops. Therefore, at 7, 8, 9, 10, 11 years, the criteria for determining the norm will not be the same as at 8 months.
Let's give an overview table containing the standards of height and girls boys and girls up to 11 years (that is, before the beginning of adolescence).
